Abstract
The Ising spin glass model in a magnetic field is studied within the Bethe and a related cluster approximations. Using replicas, spin glass order parameter function and the de Almeida–Thouless (AT) line are obtained close to the spin glass transition temperature. The results for the Bethe approximation deviate considerably from those for the Sherrington–Kirkpatrick (SK) model.
